[Attention] add gpt-oss support (#5901)

### What this PR does / why we need it?
Please refer to the following link for the historical conversation
https://github.com/vllm-project/vllm-ascend/pull/4467. We have made
updates in light of the comments from the prior PR review. Given the
refactoring of the attention_v1 component, we have carried out necessary
adjustments to fit the newly revised code.

### Does this PR introduce _any_ user-facing change?

1. Modified the code in the Attention section to adapt to the SWA and
Sink features required by gpt-oss.
2. Modified the code in the MoE section to add support for bias and
swigluoai.

### How was this patch tested?
Please refer to the
https://github.com/vllm-project/vllm-ascend/pull/4467 for performance
tests, on the basis of which the accuracy tests from AIME2024 have been
newly added.
